STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

Score
dtpADipeptide and tripeptide permease A; Proton-dependent permease that transports di- and tripeptides as well as structurally related peptidomimetics such as aminocephalosporins into the cell. Has a clear preference for dipeptides and tripeptides composed of L-amino acids, and discriminates dipeptides on the basis of the position of charges within the substrate; Belongs to the PTR2/POT transporter (TC 2.A.17) family. DtpA subfamily. (500 aa)    
Predicted Functional Partners:
essQ
Qin prophage; putative S lysis protein; Belongs to the lambda phage S protein family.
      
 0.735
gstA
Glutathionine S-transferase; Catalyzes the conjugation of reduced glutathione (GSH) to a wide number of exogenous and endogenous hydrophobic electrophiles. Shows activity toward 1-chloro-2,4-dinitrobenzene (CDNB) and ethacrynic acid. Also possesses thiol:disulfide oxidoreductase activity, using GSH to reduce bis-(2-hydroxyethyl) disulfide (HEDS). Has a low level of glutathione-dependent peroxidase activity toward cumene hydroperoxide. Is important for defense against oxidative stress, probably via its peroxidase activity. Belongs to the GST superfamily. Beta family.
      0.702
ybfP
Lipoprotein; Putative pectinase.
      
 0.678
pqiC
DUF330 family putative lipoprotein; Component of a transport pathway that contributes to membrane integrity.
      
 0.558
ysaB
Uncharacterized protein.
      
 0.527
dtpC
Dipeptide and tripeptide permease; Proton-dependent permease that transports di- and tripeptides. Shows significantly higher specificity towards dipeptides than tripeptides. Has a preference for dipeptides with a C-terminal Lys residue. Can bind Ala-Lys, Lys-Ala, Ala-Ala. Can also transport alanine and trialanine. Belongs to the PTR2/POT transporter (TC 2.A.17) family.

0.470
ybhC
acyl-CoA thioesterase, lipoprotein; Putative thioesterase. Does not bind pectin, and has no pectinesterase activity; Belongs to the pectinesterase family.
   
  
 0.468
yqhH
Outer membrane lipoprotein, Lpp paralog.
      
 0.467
